What are LECA Clay Pebbles & How To use Them
What is LECA?
LECA, which stands for "lightweight expanded clay aggregate," is a type of horticultural growing medium made from small balls of fired clay. It is often used in hydroponic systems and container gardening as a way to support plants and help them get the nutrients they need to grow. LECA has several benefits for plants, including its ability to retain water and nutrients, provide good drainage, and maintain a stable temperature. It is also relatively lightweight and easy to work with, making it a popular choice for horticulturists and home gardeners alike.
Benefits of Using LECA
Here are some benefits of using LECA for your plants:
Water retention: LECA clay pebbles can absorb and retain water, making them a useful growing medium for plants that need consistent moisture.
Nutrient delivery: The porous nature of LECA clay pebbles allows them to hold onto nutrients, which can then be slowly released to the plants as needed.
Drainage: LECA clay pebbles provide good drainage, which is important for preventing root rot and other problems caused by excess moisture.
Aeration: The spaces between the LECA clay pebbles allow for air circulation, which is essential for healthy plant growth.
Lightweight and easy to work with: LECA clay pebbles are lightweight and easy to handle, making them convenient for use in hydroponic systems and other container-based growing setups.

LECA is made from small balls of clay that are fired in a kiln at a high temperature. As the clay balls are heated, they expand and become porous, creating a material that is lightweight and has a high surface area. The process of making LECA begins by mining clay from the earth and then crushing it into small pieces. The clay is then formed into balls and dried, after which it is placed in a kiln and fired at a temperature of around 1100-1200 degrees Celsius. As the clay balls are heated, they expand and become porous, creating LECA. The finished product is a lightweight, porous material.
